Step-by-step explanation:
73.
18 = 3x (divide both sides by 3 )
6 = x ( multiply both sides by )
6 = 3x [ × = 3 ]
divide both sides by 3
x = 2
74.
24 = 2x ( divide both sides by 2 )
12 = x ( multiply both sides by )
12 = 2x ( divide both sides by 2 )
x = 6
75.
9 × x = 18 ( divide both sides by 9 )
x = 2
76.
2 = x × ( multiply both sides by )
2 = 4x ( divide both sides by 4 )
x =
